Kryo's Backpack Ice Cooling T-Shirt is the perfect low-cost cooling shirt.  We start with a heavy weight T-shirt made with 100% cotton knit fabric. Then we carefully stitch our proprietary cooling tubing to it. The result delivers superior cooling, can be worn under other clothing, and is machine washable.

You will wear the shirt with the  smooth, comfortable fabric next to your skin and the tubing on the outside.  The shirt's knit gently hugs the tubing close to your body to keep you cool.

Kryo's Backpack Ice Zip-up Cooling Vest is flame-resistant, and with its smooth front zipper, is easy to put on and take off.

Made from a single layer of comfortable, flame-resistant, hi-tech blend of 70% Modacrylic, 23% Tencel, and 7% Lycra knit, the fabric is breathable, moisture-wicking, and anti-microbial.  You will wear the vest with the  smooth, comfortable fabric next to your skin, or over a shirt, with the tubing on the outside.
